Directions

Position a rack in the upper third of the oven and preheat to 400 degrees F. Whisk the gravy and 1 tablespoon flour in a medium ovenproof skillet; bring to a simmer over medium heat, whisking frequently. Add the brisket, sauerbraten vegetables, squash, thyme, 1/2 teaspoon salt, and pepper to taste. Cook, stirring gently, until the squash is heated through, about 5 minutes. Spread the mixture in an even layer in the skillet.

Whisk the corn, eggs, cheese, the remaining 1 tablespoon flour, and pepper to taste in a bowl. Pour over the meat mixture, transfer the skillet to the oven and bake until the topping is set and browned in spots, 30 to 35 minutes. Let rest a few minutes before serving.
